(Closed) Which coworkers to invite?

So a little background so you understand my situation. I am a home care therapist, so I’m on the road 97% of the day to see my patients…there are days I dont even step into one of the two locations I work out of. I do however mainly keep in contact with CSRs in both locations. They gather all the information I need, fax/chart my completed paperwork, etc. I do have contact with them on a daily basis being in person or via email/phone.

I have decided to send Save the Dates to the CSRs I am in contact with in both locations. What I am having trouble deciding on is if I should invite my Regional Manager. I have slightly less contact with him on a day to day basis but that is due to both of us being on the road a lot.

Do I send him a Save the Date?

There are also other employees that work out of these offices I see at the same rate as the CRSs but I do not have day to day contact.

Do I invite them?

I dont know if this makes any difference but the wedding is being held on a friday evening and will be +70 minutes out of the city.

@Miss. Meeps: I really don’t think so. I got myself in a sticky situation with inviting coworkers because I used to think “all or none”, but then quickly realized that was the wrong way to go as there were many people I worked with that I didn’t want there. I myself have never heard of any etiquette rules concerning co workers.
